Interpretive Summary: Hard red spring wheat (HRSW) is an very important crop for South Dakota growers. However, HRSW production in South Dakota has decreased by nearly 50% over a recent ten-year timespan. End-users of HRSW are concerned with grain protein concentration (GPC). Growers base cultivar selection decisions heavily on grain yield potential and become concerned with GPC only when it is low enough to result in sales price discounts. It is important that HRSW breeding programs release new cultivars that balance the needs of both end-users and growers. The objective of this research was to release a HRSW cultivar possessing both high grain yield potential and GPC for SD and regional producers. The new HRSW cultivar 'Ascend-SD' was developed by the SDSU-HRSW breeding program and released by the South Dakota Agricultural Experiment Station (SDAES) to Certified seed producers in early 2022. The cross was completed during fall 2013 and the resulting population was advanced via an early-generation bulk-testing program where F4:7 seed was included in the 2018 Preliminary Yield Trial and designated as SD4873. Prior to release, SD4873 also was tested in the Advanced Yield Trial from 2019 through 2021 as well as Crop Performance Testing trials in 2020 and 2021. Ascend-SD was released for its competitive combination of high grain yield potential and GPC. This research will benefit wheat growers in South Dakota as well as the spring wheat region.

Technical Abstract: Hard Red Spring Wheat (HRSW; Triticum aestivum L). production in South Dakota has decreased by nearly 50% over a recent ten-year timespan. End-users of HRSW are concerned with grain protein concentration (GPC). Growers base cultivar selection decisions heavily on grain yield potential and become concerned with GPC only when it is low enough to result in sales price discounts. It is important that HRSW breeding programs release new cultivars that balance the needs of both end-users and growers. The objective of this research was to release a HRSW cultivar possessing both high grain yield potential and GPC for SD and regional producers. 'Ascend-SD' (Reg. No. PI 700966) was developed by the SDSU-HRSW breeding program and released by the South Dakota Agricultural Experiment Station (SDAES) to Certified seed producers in early 2022. The cross MN10261-1/SD4389 was completed during fall 2013 and the resulting population was advanced via an early-generation bulk-testing program where F4:7 seed was included in the 2018 Preliminary Yield Trial and designated as SD4873. Prior to release, SD4873 also was tested in the Advanced Yield Trial from 2019 through 2021 as well as Crop Performance Testing trials in 2020 and 2021. Ascend-SD was released for its competitive combination of high grain yield potential and GPC.
